| 摘 要： | 海洋测深大多是在移动的测量船上进行的,测量船的移动则不可避免地产生船移效应,因而船移效应是影响海洋测深精度的因素之一。在系统推证海洋测深中的船移效应模型基础上,对几种典型船速、水深、海底坡度和波束角情形下的船移效应进行了数值计算,研究了船移效应的影响规律和量级,揭示了船移效应的非对称性影响。根据海洋测深的IHO最低标准要求,提出了采用窄波束和限制船速的降低测深船移效应影响的有效方法。

| Abstract: | The depths of water are generally acquired on the moving survey vessel.It is inevitable that the effect of vessel movement is brought into being due to the movement of the survey vessel.The effect of vessel movement is one of factors that affect the accuracy of survey in bathymetry.Based on the religious deduction of the effect of vessel movement,the effect of vessel movement was calculated for cases of several typical vessel speeds,depths,bottom slopes and beam widths,and analyzed the rule and scale of the... |
